Abstract

Due to the COVID-19 pandemic, there has been an increase in the number of people infected with coronavirus and the number of infected people being indoors. In particular, infection between family members in house is serious. However, there is insufficient information on how to create an isolation room in house or how to ventilate it. Therefore, this study investigated the air flow from the isolation room to the common space and suggested a ventilation method for the isolation room. The study result showed that the ventilation port of isolation room was effective in securing the ventilation volume of isolation room. Moreover, the ventilation volume in the isolation room could be increased by operating the exhausted ventilation fan, thereby reducing the risk of infection in isolation room. This implied that air flow from isolation room to the shared space might be suppressed by operating a simple ventilation fan, so it can reduce the risk of infection in cohabit-ants of the shared space. Infection countermeasures at home differ depending on the total area, the number of people, the number of households, presence/ absence of ventilation, performance of ventilation system, and location of isolation room. Thus, measures and countermeasures under various conditions should be ad-ministered in the future.
